Application filed Setoher 6, 1913. Serial No. 793,669.

1 '0 all whom it may concern lie it known that l, ERNESTR. Sonnonona, rcsi ding at 102 East Seventeenth street, latcrson, Passaic county, New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in Lock-Lids for Journal-Boxes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate thepreferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construe-- tion shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a front elevation of the journal box with the lock or in itsclosed position. Fig. 2 is alon gitudinal vertical section thereof, taken along the line 22 of Fig. 1, the cover boss being omitted for the sake of clearness. Fig. is a plan view of the journal box, partly in section, said section being taken aloi ig the line 3-3 of Fig. 2. Fig. 4; is a fragmentary section through the upper portion of the journal box cover, taken along the line 4% of Fig. 1; and Fig. illustrates atype of key adapted to unlock the journal box cover.

During the rapid transit of trains it has frequently occurred that journal box cover hinge pins have become dislodged and the journal box covers have fallen by the way, leaving the bearings exposed to the dirt and grit swirled into the air and temporarily 'held in. suspension by the suction of the train.

it is the object of this invention to provide cover for journal boxes which may be hinged as usual, but which shall be locked in such manner that even though the cover hinge pin becomes shaken out and lost the journal box cover will be in no Wise dis- :turbed, and when desired may be opened for the inspection and oiling of the hearings or closed and locked, at'will, quite as Well as though the hinge pin were present.

Another object is to permit the complete removal of the cover whenever occasion requires it, and this may he quickly done. I The cover locks automatically when pushed in to its closed position, and cannot be, opened or removed by unauthorized persons.

- of or cnti re Because the coi'istriuctioi'i is simple and inexpensive, as well cllicicnt, it is practicable and economical to put the cov rs into use in large nun'ibcrs in equipping portions railway systems.

Referring to the drawings, the journal box 1 is of conventional fori'n, except in that the perforated hinge lug knuckle 2 has integrally cast on each end thereof an annular rib or flange 3. As shown in section in Fig. 1, the annular flange is interrupted throughout the major portion of the upper right hand quadrant of the hinge lug knuc klc L- and for a slight distance in the lower right quadrant, establishing an obliquely disposed opening 'l in the annular llange, and, it is to be understood that a similar openiug l is present on the opposite end of the hinge lugknuckle 2.

in applying the cover 5 to the journal box 1, it is first necessary to invert it, in the dire tion it ninrmally moves in when in place and being opened, until its lower edge is uppern'iost and the cover is inclined outwardly but a few degrees from the vertical. 'lhereupon, perforated partly circular bosses ll, located on the inner ends of the perfo rated cover hinge knuckles 7 are in a position to he slid into the recesses circumscribed by said annular flanges 8. Said partly circular bosses have oppositely disposed segments of the metal removed, resulting in two flat parallel surfaces spaced apart a distance slightly less than the width of the openings 4- in the flange 3 of the hinge lug knuckle 2. The axes of hinge lug knuckle 2 and the cover hinge knuckles 7 aline themselves, and the cover may then be revolved downwardly into its normal closed position. 01', if it is desired that it should remain in its normal open position for any reason, the cover may be turned down for enough for the free end of the cover spring 8 to rest upon the inclined surface 9 of the hinge lug 2 'lhcreupon, said cover will remain in its nor'nal open position until manual exertion is employed to close it.- With the cover in place, and hence with the perforated hinge knuckles 2 and 7 alined, a cover hinge pin of any suitable kind may be inserted through the perforations in said knuckles, forming an independent pivotal connection between the box and the cover. This is particularly useful in case of damage occurring to the flanges 3 or bosses 6, and forms an cllicient. temporary 2 connection. And, if, d becomes r- -cked, so as o be ely useless, any

C. B. cover available may be substituted because of the perforated hinge linucldes. And still further, should it desired to prevent the ready removal of the cover, or to hold it together in case of its becoming cracked throughout its height, the use of a pin passing through the perforated hinge knuckles of said cover and that of the box will accomplish the desired results. The rotary movement of the cover 5 will have caused the integral bosses 6 to assume a position in which their dimensions opposite the openin 's 4: in the flanges are greater than the ath of said openings and dislodginent or withdrawal of the cover 5 is impossible. In fact, any tendency to return to the initial insertingposition referred to will be resisted by the spring 8, and it can only be accomplished by a deliberate attempt on the part of a. person with that object in view. in bringing the cover 5' into its normal closed position, a latch 10, backed by a spring 11, both of which are inclosed by a housing 12 integral with cover 53, encounters the lip 13 of the outer opening of the ournal box 1 As it does so, said latch 10 recedes into the housing 12, the influence of spring 11. Upon the cover coming to in its final closed position, latch 10 snaps outwardly and behind the lip 13. locxin the cover securely in plac Latch E0 is limited in its movements by a pin 14, which passes through the cover 5, a slot 15 in said latch and the inner vertical wall of the housinglii, said pin being headed or riveted at each end. Not only does the pin 14 limit the throw of latch 10, but it retains the latter and its spring 11 within the housing 12. Besides being locked at its lower extremity, the cover 5 is also locked at its upper end, through the agency of bosses 6 and the annular flanges 3 on journal box hinge lug knuckle 2, and it is therefore closed and locked to all except those employees or others who are provided with a key to open it. Such a key is shown at 17 in Fig. 5, and also in Fig. 2, here being inserted through a keyhole 16 and into the lock Mechanism.

The manipulation of the journal box cover remains the same as in the existing practice, except that the key 15 is inserted through the key hole 16 and upon a partial turn to the right raises the latch 10 out of engagement with the lip 13 of the outer opening of the journal box. The cover may then be raised to its normal open position and held there by cover spring 8 resting upon the inclined surface 9 of the hinge lug 2 To remove the cover, manual pressure must be employed, when it will be further revolved until the flat parallel rfeces of be opened without the aid of a key to retract the latch 10.

.Vhat l claim is 1. .In a journal box, the combination of an integral .erforatcd hinge supporting lug having a knuckle portion, curved flanges on the ends of said knuckle portion, .said flanges being interrupted in their circumscription, a cover having perforated hinge knuckles, partly circular perforated bosses thereon with oppositely located cut away portions, said bosses beingnormally retained and partly inclosed by said curved flanges.

2. la a journal box, the combination of a perforated integral hinge lug, interrupted annular-flanges on the ends thereof, and a cover having perforated hinge knuckles, integral perforated bosses thereon substantially conforming, except for a pair of oppositelv located cut away segments thereof, to the inner surfaces of said flanges, the distance between said cutaway segments being than the distance between the terminals of said flanges, said flanges normally retaininp; and partly inclosing said bosses.

3. in a journal box, the combination of a hollow perforated integral hinge lug, interrupted annular flanges on the ends thereof, and a. cover having perforated. hinged knuckles, integral perforated bosses thereon conforming, except for oppositely disposed cut away portions, to that part of the inner surface of said flanges which is of uniform curvature, the distance between said cut away portions of said bosses being less than that between the terminals of said flanges, said bosses being normally embraced by said flanges, but adapted to be withdrawn therefrom. p

i. In a. journal box, the combination of a hollow perforated integral lug formed with interrupted annular integral flanges on the ends thereof, a detachable cover having'perforated hinge knuckles, integral perforated bosses thereon surrounded by said flanges except a gap between the terminals of said fumes, said bosses beingprovided with oppositely located cut away portions, the distance etween which is less than'th-at between the terminals of said flanges.

in a journal box, the combination of a perforated integral hinge lug, interrupted annular flanges formed on the ends thereof, a detachable cover having perforated hinge knuckles, integral perforated bosses there: on surrounded by said annular flanges ex cept at a gap between the terminals thereof, said bosses being provided with oppositely located cut away portions, the distance between which is less than that between the terminals of said flanges, a cover-positioning spring attached to said cover and an inclined surface on said hinge lug co-acting said integral box hinge lug, separable pivotal means partly integral with said box hinge lug and partly with said cover hinge lugs, and an auxiliary box and cover hinge connection associated with said perforations.

7. In a journal box, the combination of an integral perforated hinge lug, a detachable cover, integral hinge lugs thereon containing perforations alined with the perforations of said integral box hinge lug, auxiliary hinge elements integral with said cover, and other co-acting auxiliary hinge elements integral with said box hinge lug, all of said auxiliary hinge elements being concentric with said perforations.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.
